The "{{ project }}-zip" builder does not honor the "network" variable

[glm35]

Jenkins "{{ project }}-zip" jobs created by ansible-role-xtesting do not set the "--network={network}" option on the "docker run" command.

This leads to a failure of the "zip_campaign" command when the testapi DB cannot be reached through the default docker bridge, typically when "--network=host" is needed.

I guess this could be fixed in templates/run.yaml.j2

Remark: Maybe the "--privileged" option could be added as well, but I don't see a use case for this.
